Where is the serial number on Cleveland irons?

The serial number on Cleveland irons is typically located on the hosel, which is the part of the club that connects the clubhead to the shaft. It may be engraved or stamped on the underside of the hosel, making it less visible when the club is in a normal playing position. If you are having difficulty locating it, checking both the hosel and the sole of the club can be helpful, as some models may have the serial number in these areas.
